From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michael Trimarchi Subject: [RFC PATCH] ARM: dts: rockchip: Add wifi support for firefly Date: Fri, 7 Aug 2015 16:12:05 +0200 Message-ID: <1438956725-4188-1-git-send-email-michael@amarulasolutions.com> Return-path: Sender: linux-mmc-owner@vger.kernel.org To: heiko@sntech.de, michael@amarulasolutions.com Cc: linux-rockchip@lists.infradead.org, linux-mmc@vger.kernel.org, dianders@chromium.org, romain.perier@gmail.com List-Id: linux-rockchip.vger.kernel.org This patch enable wifi support for the firefly board. Card answer to me that support from 2.0V but regulator is connected to 1.8V, so voltage capability is wrong. In order to avoid this we just defined a fixed regulator trigger by the wifi enable gpio that report 2.0V.
